The floor of the root cellar is a clay dirt. The large stone mass is the structurally supporting chimney stack, similar to the one in the meat cellar, and it too may have had shelves inside originally. Currently the only cellar room without a brick floor, this room was used for the storage of root vegetables (like potatoes, carrots, turnips, beets or onions) and certain fruits (like apples). The original windows probably had grilles with five wooden vertical bars on the outside and wooden shutters on the inside. The shutters would have been opened only enough for proper ventilation, still keeping the room dark. Nineteenth century requirements for a properly functioning root cellar (which were probably the same as 18th century requirements) included dryness, ventilation, even and low temperatures, nearness to the place where the food is consumed, and freedom from frost. This room would have provided for all those requirements. The plaster ceiling is identical to those in the other two front rooms and served similar functions.
